UNITED- STATES mm: 0. mm, or CLAY cnmrna, KANSAS- VACUUM WATER-CIRCULATOR.

Specification of Letters Patent. Patented Aug. 17, 1920.

Application filed January 17, 1920. Serial No. 352,034.

To all whom it may concern Be it known that I, ARLEN G. Tarnon, a citizen of the Uni-ted States, res1d1n at Clay Center, in the county of Clay, tate' of Kansas, have invented certain new and useful Improvements in Vacuum Water- Circulators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as w ll enable others skilled in the art to which 1t appertains to make and use the same.

This invention relates to new and useful improvements in cooling systems and particularly to cooling systems for exploslve en ines.

he principal object of the invention 1s to provide a novel and improved a paratus by means of which a more er ect and constant circulation of water rom the engine jacket, through the radiator, and back to the jacket, can be attained.

Another object is to provide a novel and improved-water circulating system which is operative at different speeds in accordance with the speed of the engine.

Another object is to provl improved system of this character whlch as automatic in its operation;

A further object is to provide a novel and improved system of thls character which delivers moisture to the gas in the lntake manifold.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawings.

In the drawings: Figure 1 is a diagrammatic view of the system.

Fig. 2 is a sectional detail new of the vacuum tank and valve connected thereto.

Fig. 3 is a sectional detail view of the connection to the atmosphere and the valve thereof.

Referring particularly to the accompanying drawings, 10 represents the cylinder block of the engine, which has the water jacket 11. This 'acket is connected to the upper portion 0 the radiator '12by the plpe 13, and to the lower ortion of the radiator by the ipe 14. provided with t e usual filling tube 15, but engaged on this tube is a supplemental tube 16, on which is engaged the novel cap 17, used in connection with the present inde a novel and he radiator is vention. In one side of the cap supplemental tube 1s secured one end of a pipe 18 whlch passes downwardly and rearwardly where 1t 15 connected to a depending pipe 19 carried by the bottom of the suctlon or vacuum tank 20. This tank is preferably mounted on the side of the engine or cylinder block. A pipe 21 leads from this pipe 19 downwardly to discharge condensation to the ground. Ajball valve 22 is located in the juncture of the pipes 18 and 19 the I same being mounted to seat by virtue of the suction created in the tank. From the upper end of the tank a pipe 23 leads to and is tapped .into the side of the vertical leg' of the intake manifold 24, a controlling.

shut-off valve 25 being located in this pipe. Tapped into. the pipe 14, at the point of uncture with the water jacket, is an L- shaped pipe 26, the horizontal portion of wh ch opens into the water in the jacket, while the other end extends above the engine and 1s turned downwardly, as shown at 27, the latter end being open to the atmosphere,- as Wlll be readily understood from an lnspection of the drawings.

The operation may be briefly described as follows:

The engine being in motion suction will be created in the intake manifold which will draw vapor from the upper portion of the radlator, through the pipe 18, into the tank 20, and thence into the intake manifold. Tl'llS is assuming that the valve 25 is open.

The suction draws the ball valve 22 to its Water jacket will thus move in a direction toward the radiator to fill the vacuum caused by the suction through the pipe 18. As this suction continues the atmospheric air will be drawn in through the pipe 26, with the result that the ball valve 28 will be lifted from the seat, thus permitting the atmospheric air to pass through'the water and up to the space within the filling tube of the radiator, from whence it is drawn through the pipe 18. The vapor which enters the tank in excess of that used or drawn into the intake manifold, will condense and collect in the bottom of the tank. When the engine stops, the suction created by the manifold ceases, thus relieving the valve 22, which water passing out through the pipe 21 to the ground.

There is thus provided a novel and efficient cooling system wherein the water is forced to circulate through the water acket and radiator while the engine is running,

but when the engine stops the vacuum of the system is immediately filled and the excess moisture in the upper part of the radiator permitted to easily and quickly drain to the ground.

What is claimed is:

1. In a water circulation system for an explosive engine the combination with a water jacket and radiator and connections therebetween, of a vacuum tank, connections between the tank and the intake manifold of an engine, connections between the tank and the radiator above the water level therein, and valved connections between the water acket and the atmosphere.

2. In a water circulation system for explosive engines the combination with a water jacket, radiator, and intake manifold of the engine, of a vacuum tank connected to the manifold and to the radiator above the water level therein, a valved outlet from the valved inlet from the atmosphere to the water jacket.

3. In a Water circulation system for an explosive engine the combination with the water jacket and radiator and the connections therebetween and the intake manifold of the engine, of a tank located between the radiator and the manifold, a conduit connecting the radiator above its water line to the bottom of the tank, a valved extension in the conduit at the point of connection with the tank, the valve of said connection being arranged to open normally to discharge water from the tank and to close under the influence of suction in the tank, a conduit connecting ,the upper end of the tank and the manifold for creating suction in the tank under the influence of the gases passing through the manifold, and a pipe connecting the Water jacket with the atmosphere in which is disposed a valve normally closed by the water in the jacket and arranged to open to permit air to enter upon suction being produced in the system.

In testimony whereof, I afiix my signature, in the presence of two witnesses.
